A Frame -Navigational Arch

I have been searching for one for some time and I cannot seem to find one. Does anyone know of a reseller in the states? For a reasonable cost?

Thank you in advance,

JB

Hi, why not design one and get one made locally. Loads of guys this side of the pond do just that and very often works out cheaper than shop built ones. With the added advantage that it'll be custom made for your boat and will fit like a glove.

I looked for one to put onto my 14' Achilles. No joy.

Draw up what you want (including mount points), then stop by your local welders place, and see what he'll do for you. Muffler shops actually may be your best bet if you don't have a lot of marine shops around.

The tube bending may actually be the trickest part to have done. Takes a bit of skill (and usually some big-ass machine.)

Are you looking for a single tube arch, or a double? Stainless or aluminum? How thick do you want the tubes? Do you want to be able to, say, tow skiers? Or is it just for lights and antennae?

That all comes into play when you're designing the thing.

With all the Ski-boat and wake boarders over here,there are several shops who make custom arches and towers. They are used to bending high quality stainless and an A frame should be right up their street.
It's worth getting some PVC pipe (cheap over here for irrigaton use ) and warming with a paint strippergun to bend to the desired shapes. You can fabricate an arch ,to get an idea of the dimensions/anchor points etc.
If you are really good ,give the fabricator your design and say "copy this"

cheers Dal

I don't know what they use for heating pipe over in the states,if it's stainless you could use it for a A frame.


I made one for a previous boat I used S/S heating pipe, hired a pipe bender (remeber to get the springs or you will choke the pipe), measure it out on the garage floor, I used two pipes, buy some 2mm plate get it cut to size for mounts top(All round white antenna) ,sides(nav lights, spot mount) and bottom for fixings internal external use ski hooks this also gives the frame rigidity and take your time,if you are lucky to get access to a buff polish it up to a glass finish.

I've attached a wee photee so you can see

IBWet I just came across these guys at the Seattle boat show last weekend. I"m looking at their T-top but they also have an arch that bolts to the transom. I don't know what the cost would be though.

Well I've never seen a bolted one (probably better than our welded stuff) but by the cost of the accessories, the price is going to be hefty,

al is lighter than S/S which is a plus, but it's also not as strong,I'm probably wrong here but the tow frame in the picture....well lets just say that i,ve not dodged to many dinners in my day and would worry about the strength of it pulling me (as opposed to worrying about the boat which I currently do).


good idea though being able to move it from boat to boat,but I'd check the price before setting your heart on it.

They do pretty work, but I would bet they also command top (and I mean top) dollar for their stuff. They are, as I recall, pretty highly regarded on the more fishing oriented forums.

Surely you can find a local fabricator who can do pretty much the same thing (I'm assuming a RIB is not going to need a tuna tower) for a lot less money.

Holy mud! That is exactly what I am looking for!

For $599.00 seems a little out of my price range, but it looks great. Almost like the one Zodiac sells in their catalog.

Thanks Donnie!
